[PATCH v2] configs: apple: Enable SMBIOS / sysinfo

[Janne Grunau]

Enable verbose SMBIOS table generation so that user space applications
can use the SMBIOS table to provide details about the system. The
desired information is chassis-type to determine whether the system is
laptop.
Adding the chassis-type property is proposed for the upstream device
trees in the Linux kernel in [1].
Enable CMD_SMBIOS as debugging aid as the platform can easily deal with
large u-boot binaries.

I do not plan to update u-boot's in-tree device trees. The Linux device
trees have almost reached feature parity. The main missing features are
the USB Type-C ports (on track for next merge window) and the laptop
keyboards. I think it makes more sense to close the feature gap and
switch to upstream device trees instead of adding to the in-tree device
trees.
